having javascript find out the frame situation and changing it

[phoenix_fly]

Hello my code friends,

In this site I am using this zero-height frame technique to routines like drop-down-menu updating without having to refresh the main frame. But now it hit me that maybe when I air up the site, search engines may present the links to the internal pages, and so my hidden frame wonīt be present!

I thought maybe having javascript to check if the zero-height frame is present, everytime that I may need it. If it isn't, having javascript to shift the content of the frameless window into a B frame, having A as a zero-height frame...

You guys know if this is possible?

In fact, I could have this pivot-role made by a pop-up window. But the point is that the frame technique is good to hide the parameters we pass through the non-hidden frame, while the browser's adress bar shows up only our siteīs domain, you know...

I wait for your help then,

Thanks a lot

Hi phoenix_fly,

In the pages to be framed, add this piece of script:

if (top.frames.length==0) { 
 document.location= "index.html?thispage.html"; 
} 

In index.html (presuming that's the file that contains your frameset), have javascript write the frameset:

var d = document; 
if (self.parent.frames.length!= 0) 
 self.parent.location = d.location; 
a = d.location.href; 
b = a.indexOf('?'); 
if (b == -1) frUrl = 'home.html'; // default content page 
else frUrl = a.substring(b+1, a.length); 
d.writeln('<frameset rows="0,*">'); 
d.writeln(' <frame src="top.html" name="topframe">'); 
d.writeln(' <frame src="', frUrl ,'" name="mainframe">'); 
d.writeln('</frameset>');

Hey RonPK

Thanks for the reply.

My situation is a little bit more tricky: I almost donīt have html pages, as this site is heavily dinamic. So the current non-frame page (wich I have to make a frame page) can be any script.cgi with many parameters sent (through GET only, though! Thank god.)

Is there a way to implement this using the code you sent me? Or it already does that? Sorry Iīm not deeply familiar with these properties you used.

Thanks a lot

Sure, try using this in the pages you want to stick into the frameset:

if (top.frames.length == 0) {  
  document.location = "index.html?" + document.location;  
}
